unable to format partition on microSD card

[kurtkurtosis]

I created a Recovery Drive on a 64GB microSD card. Windows foramted the SD card with a 32GB FAT 32 partition. This leaves ~28GB of unallocated space according as displayed by Disk Management.

When I right click the 28GB unallocated portion of the microSD card all options to created a partion (New Simple Volume are grayed out). So there is no option to utilize the unallocated space.

Any idea how to partition the unused space on my SP3?

I did the same thing with a 64GB USB stick and created a WIN 8.1 Recovery Drive. Again right clicking on the unallocated space all options for format were grayed out.

I moved the USB stick to a WIN7 laptop and was then able to format the drive to have two partitions on the USB stick.

After that last step was your Surface able to recognize that additional space?

Yes, on the USB stick I have now two partitions: D: & E:
with D: holding the Recovery Disk and E: can be used to copy files.

I also verified that the recovery disk still works.

I can't use the microSD on the WIN7 PC as I don't have the adapter for the microSD card with me (as I am traveling).

So it sounds as if you're set, yes?

In general, yes, but can't move the microSD card right now to my WIN7 laptop since I do not have the microSD to miniSD adapter handy.

Just curious. Couldn't you put other files in the same partition as the recovery. I would have just created another folder in the recovery partition and used that folder for all my non-recovery files. I haven't ever created a thumb drive recovery setup so, I might be way off base here.
